Default Tokyo 237LVS1070 Phase linear filter plus Mixer devices data or equ internal circuit?

Hi!

The circuit page shown is from the "1 GHz Constant Amplitude Frequency Sweeper Board" of my duffy Time 9803 Oscilloscope Calibrator!

Can anyone point in the direction of data sheets for the various mixer and filter modules used on this?

Are these items likely to faulty in any way or would they last the lifetime of the Calibrator, once I've found out what the fault is?

(It's burning up resistors in various places!)
